AJ Jenkins

The 49ers and Chiefs have traded their former top draft pick wide receivers. AJ Jenkins is headed from Kansas City to San Francisco in exchange for Jon Baldwin. Viewed as underachievers, John Madden said the change of scenery might provide a boost for both of them.

With so many injuries to key receivers, the 49ers will rely more than ever on Randy Moss and first-round pick A.J. Jenkins to support top threat Michael Crabtree, starting Sunday against the Arizona Cardinals.
